Question

Find the slope of the line through each pair of points. (10.-12).(10,7)​

Answer 1

7-(-12)/10-10

19

I hope this is correct.

Answer 2

slope is undefined

Explanation:

Calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (10, - 12) and (x₂, y₂ ) = (10, 7)

m =
`(7+12)/(10-10)` =
`(19)/(0)`

Since division by zero is undefined then the slope of the line is undefined
